NEW YORK – Abbott has told its customers not to use its i-Stat Blue Chem8+ and CG4+ cartridges, following discussions with the US Food and Drug Administration.

The assays are modified versions of the White i-Stat Chem8+ and CG4+ cartridges, which were both FDA cleared and CLIA-waived. The i-Stat Chem8+ cartridge contained nine assays, while the i-Stat CG4+ cartridge had four assays.
